I didn't tell you to check vacuum lines, I told you to get a mechanic to check it with a smoke test. This will derermine if you have a cracked intake, bad intake gasket or brake booster. They inject a generated smoke from a machine and you can quickly see where you have a vacuum leak.

: D Iam glad to have profecional like you helping people in the caribbean!Ihave a couple of : 1-idle seed sensor code 35 is the same as idle cotrol valve.
2-h02s error code 13 is the same as oxigen sensor. Thanks again!

Humm the code 13 means you have an open circiut in the O2 sensor. It is probably bad. Those codes can interact with each other especially code 35.

I would replace the O2 sensor first. It's and easy job. It is a 13/16 size the same as a large spark plug. Don't mess with the wire when you take it out, cut it off right on the sensor. It will allow you to get a socket over the sensor.

When you replace it don't touch the O2 element. Use an open end 13/16 wrench to just snug it tight. It doesn't need to be really tight. The sensor unplugs from a simple connector.

Here in Biloxi, Mississippi I feel like we are on an Island. Katrina took out both bridges east and west. We have one way out North. Hope it's a better year.
